Today I tested if networking worked after what I did to the nextcube last Friday. Best way to test it is to see if it can browse the internet no? Unfortunately like almost every damn program on the machine the browser is proprietary and it had a license for it that expired in 1999. I googled for a bit to see if I could find a new key but then realized that there aren't going to be new keys. I wasn't expecting it to work but I set the clock back to 1998 and lo and behold the web browser works. So that is that. Time to get network printing working.
Also here is that comprehensive pdf I thought was from Apple but isn't. Still works fine though!
